AMD’s Big Navi 7nm GPU Flagship Allegedly Features 505mm² Large Die And RDNA2 – Suggests 2x The Performance Of The RX 5700XT

The user AquariusZi over at PC Shipping forums has been one of the most reliable source of leaks in the past and they have just posted (via KOMACHI_ENSAKA) the die sizes of AMD's upcoming 'Big Navi' lineup. The 7nm flagship in question, which could likely be called the AMD RX 5950 XT (or anything else really, AMD is free to shake things up you know), will feature a huge 505 mm² die that based on simple maths will offer at least 2x the performance of the 'smol Navi' RX 5700 XT GPU.

It's not just the Navi 21 GPU that has had its die size exposed either, the Navi 22 and Navi 23 will be clocking in at 340mm² and 240mm² respectively. Navi 23 is likely going to be a successor for the current generation flagship, the RX 5700 XT. The source has also mentioned that these measurements have an error of 5mm² give or take. Considering the RX 5700XT is exactly 251mm² the die size for the Navi 21 makes a lot of sense.

Benchmarks of an upcoming AMD next-generation GPU leaked out at CubeVR and shows an incredibly powerful card in the making. Tons of AMD cards have also recently passed RRA certification so AMD is clearly preparing an entire lineup of cards for launch. All the telltale signs of a full-blown graphics card launch from AMD are there so if you are on the market for a high-end card, you might want to wait a few months for AMD to make a move. From what we have heard, NVIDIA has also been patiently waiting on AMD to roll out their Big Navi lineup before deciding on the final pricing of their Ampere GPUs.

Twice the die size doesn't mean twice the performance...

[leadeater]

For reference TU102 is 12nm 754mm²

[Sakkura]

It's absolutely true because I read it in the Daily Mail on WCCFtech.

[Letgomyleghoe]

Finally a replacement for my rx 580, might hold off on the 5700xt

Don't forget the GV100 at 815mm².

Sort of. Twice the die size means twice the potential performance all other things being equal, but thats doesn't mean you'll get that in reality. of course this is RDNA2 so i'd be very surprised if it doesn't achieve at least a doubling in performance. Remember much of AMD's GPU woes goes back to the fact that everyone builds for CUDA but no one was building for VEGA in their software design at the gaming level. So they had to split their architecture, and whilst RDNA1 is a huge uplift AFAIk it's still not as efficient at converting raw processing performance into gaming frames as NVIDIA's alternatives.

How, we've been riding AMD hype for 30 months straight!?!?!

In fairness, the GPU hype that AMD's marketing department themselves pushed for Vega was rather exaggerated beyond the actual capabilities, unlike their CPU side where all the marketing hype that AMD themselves backed from Ryzen 1 onward was pretty on point. No major exaggerations that I can think of. However their RDNA marketing was more in line with the capabilities that were actually shown so I'd think it's unlikely that will change.

It felt like the last 3 months has been significantly better than normal.   I figured with the performance of ryzen the fanboys haven't been so wound up.

[PrinnyExplodes]

wcctech hmm. I still remember the RTX 2080 will be only $400 and have 50% more performance than a 1080ti and the fake rumors that they made up themselves to gather traffic to their website that was fairly young at the time.

 

 I go check Anandtech or Tech power up. If I don't see it, then I just call bullshit.

Yeah, and I think people are starting to get a little raw from it.

To be honest I'm quite shocked that AMD is going to be releasing a new line of GPUs a while after the previous generation. And, *gasp*, they are going to be faster!?! Damn, all these rumour sites seem to be on point with their news these days.

[Mihle]

Remember, this chip is also supped to have some sort of hardware RT capabilities if rumors are to be believed, that uses die size

The only good thing about this site is reading the idiotic comments section

[Doobeedoo]

Twice the die size and CUs along with new manufacturing process, improved architecture and performance per watt I'd expect twice the performance over RX 5700 XT as a baseline really. At least on paper for now it should be 2x+ faster.

[Bombastinator]

I just watched a video that poked various holes in both the big Navi announcement and the amphere leak.  I’m reminded of a Cold War political cartoon I saw once of Regan and Brezhnev each dressed in trench coats flashing each other with their gigantic missiles.

[williamcll]

Feels like this news was mentioned a few months ago. But it's good to see there's more confirmation. Wonder will AMD also go with Dual fans as well?

There’s a specific idiotic comments section?   Or are you referring to the comments section in general?

Yes

A specific curated idiotic comments section could be interesting.  Sort of like the “not actually news” section of the AP news wire.

i am more interested in the smaller rdna2 chip, which they claim is around 250mm²
